As described in Discussion 200

Summary: the collection returned by /edgeCloudZones?filter=closest is an array, to allow forward compatibility with other discovery calls (e.g. an array of all edgeCloudZones). The documentation in release 0.9.3 correctly shows the single array member as a MECPlatform (now edgeCloudZone object) containing two properties, however the YAML wrongly models the response as simply the properties.

Resolution: correct the schema so that the response array is an edgeCloudZone object containing the zone properties.
